Study: A handful of walnuts a day can help reduce stress Eating walnuts daily could be one of the simple, affordable dietary changes to boost brain health and overall well-being in young people, new study finds.

A study published in the scientific journal Nutrients by researchers at the University of South Australia found that eating two ounces (approximately 57 grams) of walnuts per day for 16 weeks by university students improved their mental health scores.. The study involved students from 18 to 35 years old..

This dietary change also had a protective effect against some of the negative effects of academic stress and improved sleep quality in the long term..

Walnuts are known for promoting health as they contain healthy unsaturated fats and are rich in omega-3 alpha-linolenic acid.. They also have a unique combination of bioactive nutrients and phytochemicals that may underlie the mental health benefits seen in research..

“In addition, studies have shown that increasing the diet of tryptophan, which is used by the brain to produce serotonin (a natural mood stabilizer), leads to a decrease in symptoms of anxiety and depression,” said Larisa Bobrovskaya, Associate Professor of Clinical and Medical Sciences at the University of South Australia and presenter. “Thus, the presence of tryptophan in walnuts may have also contributed to these results.”.

The researchers noted that further work is needed to better understand the mechanisms by which a diet that includes walnuts can affect the brain and mental health..
